Feedback on our landing page (Flashcards app)

Hey IH,

We've recently been working on Pariksha (http://pariksha.io), a app to create flashcards and take mini assessments. I've seen a similar post here asking for a critique of the landing page and what can be improved, and I'm hoping to collect some feedback.

The main goal is to collect emails for when we launch the app. We've yet to do a hard marketing push and I'd love to iterate on people's feedback before doing so.

At present we have a functional landing page with a demo of the flashcard product and we are working on a back-end so that our customers can create their quizzes easily in 3 steps.

Here is the sneak peek video of flashcards creation interface

Please keep your feedback coming.

Thank you in advance

Shirish
